School officials believed their work was finally done after a $28 million remediation and a six-year legal battle, but on Thursday, when more mold was discovered on the campus, that price tag was expected to go up once again, the article stated.

According to the article, the mold, which was discovered during routine maintenance, was revealed to be black mold, which can be toxic to the health, and officials aren’t certain how long the mold has been there.

"It''s been there awhile. There''s really no way to tell exactly, but it''s been there long enough that the metal studs on the wall are rusted. So far we know about that wall, and we’ll be checking the other outside walls and the ceiling of this building. We''re pretty sure it''s not on the inside walls," said Superintendent Don Schlomann.

The mold problem has cost the district nearly $30 million to fix and a handful of students have sued the district citing health problems related to the mold, winning a combined settlement of less than $100,000 after a six-year legal battle, the article noted.

"Now we''re real sensitive in this community about that four-letter word — mold. We want to be real open and make sure people know this is what we found, and we’re thinking about safety for everyone. Any time you find mold anywhere in a building, it’s a big thing. We need to make sure we treat it like that," Schlomann added.
